TO ALL WHOM'IT MAY CONCERN:

Be it knownv that I, JOVEN M. CANTERBURY, oi Mexico, in the county of Andrieu, and Stuterof Missouri, have invented a new and useful Improvement in Field-Marker; und I dol hereby deelne-that thefollowing is s'- full, clear, and exectdescription thereof', which will enable those skilled in the art to multe and use the same, reference being hud to theY accompanying drawings, ,forming part of this specification, in which the drawings represents a pluri of my improved revolving field-marker.

This inventipn relates to un improvement in the construction of a. machine .for marking rows for-planting corn or other Iseed in field-culture, and consists in a wid'andat'frume, n'ithinwhich is suspended a. number of cost-iron wheels in such a manner-theta they` can be adjusted to work at di'orent distances apart, und mark rows of different width, as ma'y be required; nrndalso'in forming the periphery in such'n manner that the wheel shall not sink too deeply in the ground vi'hen the soil is niet and soft, as'hereinnfter more purt'iculnrly described.

A A represent e'wide frame,V divided into spaces for suspending marking-wheels B B B on spindles :La a. The wheels will be made of cast iron, about two feet in diameter, with a. rim about three inches wide, two and one-half inches deep. The middle of the perimeter will be made shurp, and bevelled on"both sides,'with uflange on each side, as shown sectionally in the drawing. p l

This form will make a distinctly-marked trench, with sloping sides, in the ground, whenrthewhe'el revolves, while the wheel will be upheld by the flanges, and cannot sink too deeply inthe soil when soft. Thenuxrlber of the wheels may be 4varied.

I shown and described.

For adjusting the wheels' B B to .different widths, they muy he moved orf the spindles a a nearer together or further apart, and are held in any position by set-screws 'b through the hub. The frame A A is provided with a tongue, C, and u seat, D, for the driver; and the machine thus constructed is simple, cheap, and strong, and is very e'ective and durable in operation. V l

Having described my invention, I claim as nerf, and desire to secure Yby Letters Potent-4,

l The cust-metal wheel B, having a. shurp-hevelledperimeter, with square shoulders upon enchfsde, when adjusted upon the spindle a, by means of the set-screw b passing through the' hub of sai-d wheel, as herein JOHN M. oA'NrERnnRr;
